By referring to Figure 1 it is seen that the draft roll l9 has a sprocket fixedly mounted there- 5 on upon which is mounted a sprocket chain 36, said chain 36 being adapted to rotate on a second sprocket 31 which is of the same size as sprocket 35. This sprocket 3! is fixedly mounted the upper portion of a spinning frame showing myinvention applied thereto;

It should be noted that the rolls n said rd I 3 is a. pp in member 14 38 andfldl have restricted portions 38a and Ma 50 which projects upwardly and supports creel respectively, which allows the butt end of holddS a The Spinning frame 5!! D- er 42 to pass between these rolls when the roving ports a longitudinal angular member I! upon has been exhausted. This feature also allows the which are mounted a plurality of roll stands l8 roving holder such as a quill 42 to be supported having conventional lower draft rolls I 9, 20 and in a horizontal position at all times by the rolls 55 38 and 4| when the roving on the quill has become almost exhausted.

When the quill 42 is filled with roving 43, as shown in Figure 3, the roving is fed from this quill 42 since the sprocket chain 36 is driven by the rear draft roll [9 and this sprocket chain also turns the roll 38 to cause the packages to rotate in a like manner. The roving 43 passes from the quill 42 over the longitudinal shaft 44 which is also mounted on the roll stand l8 and then through a suitable hole in oscillating bar 45. The roving 43 is then passed between the draft rolls l9 and 24 inclusive, and onto quill 28.

A longitudinal shaft 46 is fixedly mounted in supports 39 and 48 and is adapted to cooperate with a leaf 48 rotatably mounted on'shaft 4?, which shaft is fixedly mounted in members 39 and 48.

It will be noted in Figure 3 that the left-hand end of leaf 48 is heavier than the right-hand end and when there is no Weight resting on the righthand end thereof the leaf 48 will assume a horizontal position and rest against the pin 58 in sidewall 39. When a package 49 of roving is placed between the leaf 48 and the shaft 46, a suitable lever 5| is adapted to have its upper hooked portion engage the left-hand portion of the leaf 48 and to hold it in a horizontal position. The lever 5| is mounted for oscillation on a shaft 52, said shaft 52 being fixedly mounted in sidewalls 39 and 46.

The lower end of lever 5| has a link 53 pivotally 7 connected thereto which link projects to the left in Figure 3 and is pivotally connected to the upper end of a lever 54 secured to leaf 55. A spring 56 has one end thereof secured to leaf and the other end secured to the sidewall 39 to normally hold the leaf 58 in the position shown in Figure 3. Leaf 55 is mounted for oscillation on longitudinal shaft 58 which in turn is fixedly secured in members 39 and 48.

The leaf 55 also has an upwardly projecting lever 59 which has pivotally secured to the upper end thereof a horizontally disposed link 69, said link 68 projecting to the left and being pivotally mounted on the lower end of a lever 6|. Lever 6| is pivotally mounted on shaft 62, said .shaft 62 being fixedly mounted between. sidewalls 39 and 48 and the upper end of lever 6| is adapted to slidably contact a pin 63 fixedly secured in stationary jaw 64 of roving clamp 65. This clamp 65 has a movable lowerjaw 66 pivoted thereto by pin '67 and a suitable torsion spring 68 isadapted to be confined around the pin 61 and engage the movable jaw 66 to normally force it at all times against the lower end of stationary jaw 64 to clamp roving 49a.

The clamp 65 is secured to a block H1 which in turn is slidably mounted on a pin 17' having an enlarged head portion 18 and being secured in traverse bar 45. A spring 19 has one end thereof secured to the block 18 and its other end-secured to the enlarged portion 18 of pin Hand it is seen that this spring will normally pull clamp 65 to the right in Figure 3. When the roving 43 has all been removed from the spool or quill 42, the quill will pass between the rolls 38 and 4| and fall upon the leaf 55 (see Fig. 3). When this is done the leaf 55 will assume the dotted line position and cause the members '54, 53, 5|, and 48 to likewise assume the dotted line position, thereby allowing the package of roving 49 to fall downwardly and be guided to a position which the roving 43 and spool 42 now occupy in Figure 3 by means of suitable guides 8|] secured to the sidewall members.

The members 88 are adapted to support the ends of the spool and prevent it from falling out of its proper path. It will be noted that the package of yarn or roving 49 has the end of its strand 49a engaged by the clamp 65. At the same time that the packaged yarn or roving 49 is allowed to move downwardly onto the rollers 38 and 4| the link 66 will be moved to the right in Figure 3, thereby causing the upper end of lever 6| to force the pin 63 and the clamp 65 to the left.

When the end of the roving 49a has been presented to the draft rolls I9 and 22, the beveled prong 82 on the bottom of movable jaw 66, will engage shaft 44 and cause the clamp 65 to release the end of the strand 49a. It is therefore seen that the strands on the package 49 will then be fed to the rolls in the same manner that the strand 43, which is on spool 42 was fed previously. It should be noted that clamp 65 is secured to oscillating bar 45 and is adapted to oscillate with the bar.

Lever 6| is stationary but the upper end thereof has a sliding contact on the pin 63 which will allow this oscillation to take place without interfering with the stationary parts. The upper unit 3| is similar in most respects to unit 36, just described, and a description of these parts is not deemed necessary, but it might be stated that similar parts will bear like reference characters with the prime notation added. However, it should be noted that a slightly different arrangement must be made for the operation of this unit with its clamp 85 which is shown in Figure 4 and which is similar in all respects to the clamp 65 just described and has identical reference characters.

The lower end of leaf 55 has integral therewith an arm 86 having a slot 86:: in the lower end thereof. The upper end of a lever 81 has a bolt therein which penetrates this slot. Lever 81 is pivotally mounted on a longitudinal, horizontally disposed shaft 88. This shaft 88 .is likewise mounted in end walls 39 and 40 and the lower end of lever 81 is pivotally secured to horizontally disposed link 68, (see Fig. 4).

When the quill 42' has its roving exhausted therefrom, it will pass between the rollers 38' and 4| and fall upon the leaf- 55 to cause this leaf to assume the dotted line position. This, in turn, will cause arm 86 and the lever 81 to assume their dotted line position and thereby causing the lever 8'! to rotate a slight amount in a counter-clockwise manner. This rotation will I move the link in Figure 4, to the right which will cause counter-clockwise motion of lever 6| thereby pushing the clamp 85 to the left of pin 7 TI and introducing the strand 49a. to the draft rolls l9 and 22. It is evident that when the quill falls off of the leaf 55 that the spring 56' will cause the leaf 55' to assume the horizontal position and thereby cause the lever 5| to latch the leaf 46 in, its original position, since the lefthand end of leaf 48" is heavier than the right with the lower unit 30 and at the same rate of speed by means of sprocket which is mounted on restricted portion 38a. A suitable chain 9| is mounted on sprocket 90 and also on another sprocket 92 which is identical to sprocket 90, said sprocket 92 being fixedly mounted on the end of restricted portion 38a.

The upper units 3| feed their rovings to alternate sets of bosses on the drawing rolls while the lower units 30 deliver their rovings to the other bosses on the drawing rolls. There is one roving fed from a unit at a time while a second roving has its end held by the clamp for feeding it to the bosses upon exhaustion of the roving being fed through the set of bosses.

In the drawings and specification there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being set forth in the appended claims.

I claim:

1. In a roving frame, spinning frame and the like having drafting rolls, a pair of spaced rollers driven by the drafting rolls for supporting packages of rovings, other means for supporting a package of rovings, means for engaging the end of the rovings on said other package and feeding same to the drafting rolls, means operable upon exhaustion of the rovings on the first package for releasing the second package, means for guiding the second package onto said spaced rollers, and

means for moving the means engaging the end of the roving on said second package to feed its roving into the drafting rolls.

2. In fiber preparation machinery having drafting rolls, means for holding a package of fibers in strand form, means for turning the package to feed the strand thereon into the drafting rolls, other means for holding a second package in reserve, feeding means for engaging the end of a strand on said other package, and means operable upon exhaustion of the strand on the first package for moving the second package into the position occupied by the first package and also moving the feeding means to cause its strand to be fed to the drafting rolls.

3. In fiber preparation machinery having drafting rolls, a pair of spaced rollers driven in timed relation to the drafting rolls and being adapted to support a holder filled with rovings thereon, a trap door mechanism for holding a second holder filled with rovings, a chute for guiding said second holder onto said rollers, clamp means for holding the end of the roving on said second holder, means operable by the holder of the first package when it falls between the spaced rollers upon exhaustion of the rovings thereon for tripping said trap door mechanism to cause the second holder to move onto said spaced rollers and to move the clamp means towards the drafting rolls to feed the end of the roving from the second holder to the drafting rolls.
